Combined Gradation Example mdtmtgovPROJECT PROFILE ON CEMENT CONCRETE HOLLOW BLOCKS
Concrete Aggregate Combined Gradation Example General MDT is moving toward optimized gradations for concrete aggregate This example presents some basic computations for optimizing a blend of multiple aggregat Included is the production of three optimization charts that may be required to be included in the concrete mixNatural sand is often used as fine aggregate in cement concrete mixture Coarse aggregate are crushed stone chips Crushed stone chips broken into particle sizes passing through the 47 mm sieve may also be used as fine aggregate The maximum size of the coarse aggregate that may be used in cement concrete hollow blocks is 125 mm
